Question

I have two lines of call command in batch file like this:

call execute.cmd
call launch.cmd

My need is to call the launch.cmd if and only if call to execute.cmd succeeds.
So is there any way by which can I put some condition here?

execute.cmd does not return any value here.

Answer 1

If execute.cmd returns an integer than you can use a IF command to check it’s return value and if it matches the desired one than you can call launch.cmd

Suppose that execute.cmd returns 0 if it is successful or an integer >= 1 otherwise. The batch would look like this:

rem call the execute command
call execute.cmd
rem check the return value (referred here as errorlevel)
if %ERRORLEVEL% ==1 GOTO noexecute
rem call the launch command
call launch.cmd

:noexecute
rem since we got here, launch is no longer going to be executed

note that the rem command is used for comments.
